the totalizer resetting mechanism. Fig. 9 is a detail of a device by means of which the detachable accounting device may be latched to the machine. Fig. 10 is a top plan vie\v ot' the machine. Fig. 1l is a top plan view of a detachable accounting device with its casing in section. Fig. 12 is a transverse vertical section of a detachable accounting device.

In the following detailed description the various mechanisms relating to the invention will be described in the following order: First the construction of the detachable accounting devices will be brieiy refer red to:

then the auditing machine will be described,

starting with slides which coact ivith slides of the detachable accounting devices and serve to' position type carriers and segment gears, by means of which a totalizer of the machine is actuated; then the printing mechanism, in order to show hoiv detailed records are made of the differential settings which the slides of the machine receive from the detachable accounting devices; then the to talizer, with means for meshing and unmeshing-the totalizer with its actuators; the manner in which the-totaliaer of the auditing machine is reset, and how .pon resetting of this totalizer a record is printed ot' the total accumulated by it; and finally the manner in which the detachable accounting devices are reset.

A detachable accounting device is illus-- trated in Figs. ll and 1Q. It comprises a Jframe. 1l livithin which is slidabl'v mounted a fset -ot' denominational slides 2. These slides are normall)v1 spring dran-n to their outer or nine positions. The slides ina- V be differentially positioned b v coacting slides ot suitably constructed cash registers and are locked in their set positions bv a plate 3 which, for this purpose, is provided with a pointed flange 4. engagingnotches 5 in the slides. Then the slides are diiierentiallv positioned the plate 3 is rocked upon its pivot G to release the slides b v a plunger which lis mounted in the operating machine and ivhich enters an opening i' in the casing of the` device. The unlocking movement .ot the plate 3 is normalh7 preventedb.Y identii living blades 8, the upper edges of which are provided with notches l0 which are normall)Y out of alinement with the Bange 9.

therefore. in order to unlock the denomina' so that their notches register with the flange 9. The operating machines are provided with means for correctly positioning the blades. v

As previously stated, the present invention relates to means for accumulating the totals of a plurality of detachable accounti Ptioned in correspondence with the setting fthe denominational slides 2. The slides 33 arenormally held in their upper or zero positions, as indicated in Fig. l, by springs 12 and the Jfarther the slides 2 are away from their Zero positions the greater will be the extent of" movement of the slides 33. These slides are provided with two sets of rack teeth 13 and 14 which respectively c"mesh Withv segment gears 15 and 16.V The segment gears 15 are secured to type carriers 17, therefore'these type carriers willA -be set according to theextents of downlward movement of the slides 33. The zero 'character is normally ata printing line.

18. One unit of downward movement of a slide 33 will bring the one character to the printing line, whereas nine units, or the :full extent of possible downward movement of a slide 33, will bring the nine character to the printing line.

T heprinting mechanism is illustrated in' side elevation in Fig. 2. In this view a ,roll of detail paper 19 is shown and the ypaper leads from this roll to feed rolls 20 and 21 and ,from these vrolls between the type carriers 17 and a platen 22, out of the machine. The platen 22 is carried by a pair of members 24 which are slidably mounted upon a shaft 25 and av rod 26, and are connected together at their rear ends by a rod 27. This rod passes through an 'arm 28 fast on a shaft' 29 which lshaft also ycarries rigidly an arm 30 extending between pins A31 and 32 of a hell crank lever 34 loose on shaft 2.9 andwhich carries a roller 35 coactinglwith a platen operating cam 36. The roller' 3 5 is carried by an arm l,3,7 which is pi .voted to the bell crank lever 34 'for the purpose 'o'' alloifving a slight rocking movement of the arm around its pivot. It is limited lin this rocking movement by pms 38 'and39ad theobject'f Somounti a link 71.

A)ing the"v roller 351s topermit a, quick actionI ofthe' platen 'bya'springe 'as soon as the high part 41 of the cam passes the center line thi-ouah drive shaft 42 and the roll 35. At sucn time the arm 37 rocks slightly in the direction. indicated by an arrow 43 under the action of spring 40 carrying the roller 35 well clear of the cam.

The paper feed rolls are rotated the required extents and at the proper time by a cam 46 which is carried by the drive shaft and which operates a pitman 47 connecting this cam with a plate 48 which is loosely carried by a shaft 49 and is connected by a link 50 with an arm .51 loosely carried by a shaft 52 upon which is rigidly mounted the feed roll 21. The arm 51 is provided witha pawl engaging a ratchet wheel 54 last on the -t'eed roll 21. The companion feed roll 20 is journaled upon an eccentric sleeve 55 around a shaft 56 and this shaft carries an arm which at thev time of threading detail paper between the rolls 2O and 21 is rocked downwardly to carry theroll 2O away from the roll 21.

Printing is done through an mk ribbonl 5S) which passes between the detail paper and the type carriers from an ink ribbon spool 60 to a spool 61, these spools being respectivelycarried by the shaft-49 and a shaft 62. These rolls are rigid-With ratchet wheels 63 and 64 and arerespectively actuated by pawls 65 and 66, one ofwhich' is carried by the plate 48 and the other byA a lever 67 which is connected tothe plate 48 by a link 68, therefore the lever 67 is also l rocked upon the rocking of the lever 48 but only one of the pawls is in engagement ioo `at a time, the pawls being alternately rocked into and out of engagement for the purpose of reversing the direction of feed of the ink ribbon.

Pivot pins 69 of the pawls carry small arms 70 which are connected together by This link may be reciprocated in a vertical direction for rocking one or the other of the pawls into engagement with its respective ratchet. In Fig. 2 the link is in its lower position with the pawl 66 in engagement and the pawl 65 out of engagement.- The link is held in this position either by its own weight or a lightspring but may be moved upwardly for the purpose of reversing the enga oement of the pa-Wlsby tensioning a. spring 72 which connects the link 71 with a 'pin'73 ona toothed wheel 74. The spring 72 is alternately tensioned and released by rotating the Wheel 74. This Wheel is rotated at a rate Which v-corresponds to the length of ink ribbonby a pin 75 which is carried by a ratchet Wheel 76 and causes the wheel l74 to rotate one tooth space upon each complete rotation of' the ratchet wheel 76. The ratchet Wheel 76 is actuatedbyapawl 77 which isc'ar- .ried by: an arm '78,.alvnd *this arm is ,con- 'nected by 'avlink 79, tothe plate 48, the

rocking of which was previously explained. As there are twelve teeth to the particular' ratchet 76 which is shown. it takes twelve .a cam 190 causes the operations of the machine to cause the wheel 7l to rotate one tooth space. For this rea son a considerable number of operations of the machine is required in order to reverse the direction of feed of the ink ribbon.

'otalz'eer. totalizer 80 (Fig. '1) is adapted to accumulate the totals of any desired number of detachable accounting de vices and to this end receives differential rotation from the segments 16 each time a detachable accounting device is inserted into the machine. It was previously stated how the segments 16 receive dife'rential rotation from the slides 33 doesnot mesh with its actuating racks 91 upon the down-stroke of the slides 33, but is meshed with the racks turn movement of the slides. To this end the driving mechanism controls means for locking the slides 33 for a certain period during each operation of the machine and means for meshing the totalizer at this time. The operating mechanism is so arranged that after the totalizer is meshed the slides 33 become unlocked and are then restored to their zero positions thus causing the totalizer pinions to be rotated extents which correspond to the extents of movement of the slides 33.

The slides 33 are locked in their moved `positions bymeans of alining pawls 8l which are carried by a shaft 82 and coact with toothed segments 83 which are rigid with the type lcarriers 17, pawls 81 are all secured to and this shaft also carries an arm 84 (Fig. 2) which is connected by a link 85, arm 86, shaft 87, arm 8S, and pitman 89 (Fig. l) to a cam on the drive shaft 42. It may be seen from Fig. 1 that this cam is arranged to rock the alining pawls 81 into engagement with the segments 83 soon after the beginning of the operation of the machine, when the platen 1s operated. A cam 96 (Fig. 3) also causes a pitman 97 to be4 lifted thereby rocking the totalizer 80 into mesh with the actuating racks 91. The pitman 97 is connected at its lower end to an arm 98 fast on a shaft 99, to which a totalizcer carrying frame 100 is rigidly secured.

It not desirable to rely upon cam 96 for regulating the exact positioning of the totalizer when the cam rocks it into mesh with the actuating segments. An alining device (Fig. el) is therefore provided, consisting of a pawl 188 coacting with a V shaped notch 189 in the totalizer carrying frame 100. After the totalizer is in mesh pawl to enter the notch 189 and'thereby in the desired position The totalizer 91 during the re' and upon the vments 16 the rive at their home The alining the shaft 82v lvarious amounts ltransfer or carrying devices. Each 'totalizer centers the totalizer` preventing .frieden which is carried by arms 102 on the shaft 25, is rocked around this shaft far enough to cause the type carriers 17 to be restored to normal or zero position through engagement vwith upper edges ,103 (Fig. l) of the type carriers. When the type carriers are moved away from their zero positions upon the insertion of a detachable accountingl device the rod 101 is carried upwardly through engagement with the upper edges of the type carriers. This rod is pivoted to a pitman 92 (Fig. 5)\Which is provided with a roll 93 coacting with 'a cam 9-1 which is carried by the drive shaft 12, `but the cam is normally not in the path of the roll v93 and, therefore, does not interfere with pitman upon insertion of'.

The

movement of the the detachable accounting devices. racks and segment gears 16, as they are geared to the type carriers, are returned to their zero positions with the type carriers return movement of the'segracks 91, which the segments carry, cause the desired rotation of the totalizer pinions. After the segments arposition the totalizer is rocked out of engagement and is in, condition for the next operation of the machine at which time it is further differentiallyv rotated in the same direction thereby successively accumulating the amounts which are carried by the detachable accounting devlces.

As the totalizer successively accumulates it is necessary to provide pinion 10A-l, except the pinion of highest order, carries two liametrically opposite pins 105 which serve to engage and actuate transfer devices each time a pinion completes ten units of rotation. Thesetransfer devices include paWls-106 which are pivoted loosely upon a red 107 ofthe totalizer frame and are normally held by springs at rest against pins 109 as indicated in Fig. 1, and are located in the same vertical planes with depressible plates 110 eachrof which is carried b v the segment 16 which is of next higher dencn'iinational order than the pinion 104 which carries the pins 105 enacting with the particular transfer pawl 106. When a. pawl is rocked rearwardly it causes the depression ofthe coacting plate 1.10 thereby rocking a pawl 111, which is carried by the segment 16, rearwardly as a shfulder 112 of the pawl engages the upper si le of the depressible plate 110. The 'pa wl carries a pin 113 which normally engages a shoulderll on .its rei invention described in a patent applicationA V spective rack 91 and, therefore, prevents movement of the rack relatively to the segment 16 under the action of a spring 115, but when 'the pawl is rocked rearwardly upon transferring operations, the rack springs oneA tooth space relatively to the segment 16 and in the direction indicated by an arrow 117.

After the totalizeris unmeshed the racks 91, whichare in tripped position, are resto-red to their normal urelation with the seg- 'ments 16 by a rod 118 which extends across edges 119 of the .racks and is carried by a paircf arms 120 (Fig. 6) on the shaft 26. This shaft also carries an arm 121 which is connected by a pitman 122 with a restoring cam 123 on main shaft 42.

This transfer mechanism is not novel in the present invention, but forms part of the filed by E. S. Church, Serial No. 539,834, on Jan., 24. 1910, and describing a machine especially adapted for department stores.

To reset the totalizer and to transfer its settings to the type carriers so that the grand totals which it accumulates may be printed, the totalizer pinions are each provided With -pawls 124 (Fig. 1) which. when the totalizers ar'e normally operated in a forward direction as indicated by arrow 125, -idly slide around the periphery of totalizer shaft 126 but the totalizer shaft is provided Witha plurality of notches 127 (Figs. 1 and 7) for the purpose of engaging the pawls upon resetting operations and backvvardly rotating the totalizer pinions to `their home positions.` These notches` are not'normally in the line of movement of the pawls 124,.

' therefore in, order 'to resetthe -totalizer it is the totalizer shaft 126. By rocking the lever necessary to shift the shaft-126m a longitudinal direction, sopthat the notchesand pawls will come into coacting relation. This shifting of the shaft is accomplished by a yoked'lever 128 (Figs. 7 and 8) which is securedvto astub shaft 129, and anges 130 and 131 of which extend over the ends of 128 inthe direction of arrowl .132 the shaft 126 is slid in the totalizer frame 100 as desired for resetting purposes.

The resetting is accomplished by rotating the totalizer shaft 126 a. half rotation oppositely to the direction indicated by the arrow 125 (Fig. 1) and while the totalizer pinions lare in mesh with the racks 91 so that the type carriers .will be set properly for printing the total. It is of course essential upon resetting operations that no detachable ac-' counting device be in the opening 11'of the 6(-) 1nacl1ine, because if it were,.free action of the segments 16 and the type 'carrierswould be prevented. For thisv reason the machine is provided with a.shutter133 f`(Figs. 1' and 10) forthe opening 11 ywhich :fi's z-lunden.v the If -control ofle'ver 134.y (Fig. vv7)y bywhich-the vp 129 is rocket' A etarra@ to the yoke 128 by a pin 136 and connects the yoke Kto an arm 137 on a shaft 138. This shaft carries an arm 139 which extends upl Wardly through a cut 140 (Fig. 10) in the shutter 133,which is slidably mounted on a `top plate 141 'of the machine by means of pins 142 which extend through a slot `143`in the shutter. When the lever 134 is rocked to the right the arm 139 forces the shutter over the opening 11. It isthen impossible to insert a detachable accounting device While the lever 134 is in its moved position. If a detachable' accounting. device is in place and it is attempted to shift the lever 134 to the right,

the accounting device, of course, blocks movementof the shutter and, therefore, prevents the operation of the lever. For the purpose of rotating the totalizer shaft upon resetting 145 performs no function, but upon total printing or resetting operations the oscillation ofthe totaliz'er shaft causes the totalizer pinions to beA reset to vZero positions. This occurs while the totalizer is in mesh with the racks 89, as previously sta-ted, andthe printing of the' total is accomplished 'by the usual operation of the platen.

In order that upon resetting operations the downward movement of slides 33, as effected by a reverse rotation of the totalizer pinions, may occur before the operation of the platen and the restoring movement of rod 101 (Fig. 5), these opera-tions are,de

layed more than would be necessary inf the more common operation of adding amounts to the totalizer. Also in the matter of engagement ofthe totalizer, resetting operations require that it be disengaged on-the restoring movement of rod 161, 'while in adding operations it is at suchtime engaged,

but in order to make a singlecam serve the purpose of engaging the totalizer on both operations, and also to simplify the mechanism, -the cam 96 (Fig. 3) is arranged to engage and disengage the totalizer twice upon each operation of the machine. The first meshing and unmeshing serves to hold the totalizer'in mesh thecorrect length of time for ordinary operations of the machine rit when detachable accounting devices are in 'serted The second'A meshing unmeshing A at-such.times is merely idle. Upon total krinting.operationsthe rst meshing of the ltotalizerns:,employed for setting the type I of the :totalizer,

operations of the machine and in the other :carriers and when set the total is printed but pinions are brought back to the totalizer their original positions before being unmes'hed; upon the second meshing of the to-A ing in mechanism, also permits a printing of a subtotal, as the resetting lever 134 may be shifted to its normal position after the irst.

meshingand unmeshing of the totalizer, and

when the dri-ve shaft has made about onehalf of a rotation.

The difference between the tivo operations in one case upon ordinary case upon total printing operations, is that v1n theifirst case the totalizermiist he held in mesh only upon the `restoring of the'diflerentia'l mechanism while in the other case 4the totalizer must be held in mesh during the resetting of the ltotalizer, but it should be outl of mesh upon the restoring of the di fferential mechanism. The first half of the cam 96 is formed to hold the totalizer in mesh during the restoring of the differential mechanism. The second half of the cam is, therefore, so formed that the totalizer Will be held in mesh diiring the resetting of the totalizer pinions but out of mesh upon the second restoring of the differential mechanisin, which occurs by 12 (Fig. 1) when the alining devices 81 are caused to release the type carriers by high part 95 of cam 90 passing away from the roller on pitnianA 89. .To state this diiferently,- upon ordinary operations of the mathe action of springs .chine when a detachable accounting device is in the machine, the totalizer pinions are rotated upon restoring the differential mechanismto zero position.. Upon resetting opcrations the totalizer pinions are backivardly rotated While the diiierential mechanism is moving forwardly, therefore if the totalizer pinions remain in Vmesh during the return of the diiferential mechanism, they ivill be rotatedfback to their former reading. This is what occurs during the first half rotation of Ithe drive shaft upon resetting operations, but the continued rotation of the.

drive shaft causes another part of the cam 96 to rock the totalizer into and out of mesh, though this part of the cam 96- serves to'hold the totalizer in mesh only duri-ng the upstroke of the segment 145, and by this construction the totalizer remains in its reset position at the completion of the operation of the machine. Because 'of this arrangementthe cam 147 is arranged to oscillate the segment gear 145 twice upon 'each operation of the machine, as maybe seen from Fig. which illustrates this cam. l

The particular type carriers v12' which are controlled in their movement by'- the identifying blades of the detachable accounting' is connected van arm 155 Whichpis' .pirated devices are provided vwith blank spaces which are'opposite the printing line when in their home'position, for the purpose of preventing an impression from these type carriers upon resettingl operations.

In the particular machine shown there 4are six amount slides 83 but it is desirable to have tivo or'three more ltotalize: Wheels 80, to permit .addition of large amounts properly. With the type of machine shown, additional rack segments 91 are provided for these higher wheels but these higher segments'arel ever, that if the carrying'A segments of these' higherorders were free -to move, a transferring movement of a rack 91 might, by

inertia, displace its carrying segment 16. To prevent this false movement, these igher order segments 16 are normally locked against inovementby a fiange 195 on an 'arm 1941, journaled on .shaft 29, this fiange normally resting against edges 196`of these higher order segments 16. These segments must he permitted to operate t'o print a total from the totalizer properly, however, and to this end the arm 11i-'iis actuated by the resetting lever 134 as its end rides in a cam slot 197 in an arm fast to the Vlever 134. Thus when the lever 1341's moved to cause resetting of the totalizer, the flange 195 is Withdrawn from the segments 16 and' they properly. Of course In order to distinguish the printed grand total. from the totals of individual detachable. accounting devices a special vtype carrier 198 Fig. 8) is provided. This carrier through a link 199, a lever 200, i and a link 201 to one arm of the voked lever 128 andgwhen this lever is shifted to the resetting position the type lcarrier 19S is rocked sothat a speeialfcharacter 202 is brought to the printing line. g

In order tourment-Withdrawal of. a de'- tachable accounting device when onel is in the machine and the drive theY machine is provided' (Fig. 1) eoaeting With shoulderedplates` 151 of the detachable accounting devices. When one of the detachable'accounting devices is no transfer ever takes place at a' table printing operation.

shaft is rotating, With 'a' latch 150 inserted finto the machineit's-front edge engages a'i'joller 152 ivhich extends across a shoulder 153'of a slide 154 which Acarries the latch 150. .Theroller 159 'is carried bv noon a shaft nnerfoo'siti/iii 156 and normally yheldin its u as shown in Fig.l 1,- bv a springv 157. The insertion. of the detachable device, thereward movement of the slide 150 the arm- 160 is rocked out of the path of the shoulder 158 against the action of a spring 162 (Fig. 9) which is extended between the top plateof the machine and an arm 163 on the' shaft 161. This arm is pivoted at its outer end to a pitman 164C which carries a roll 165 extending into a. racef166 of a cam 167.

The -race of the ca-m is broadened at the point of the roll 165 adjacent the cam in its normal position for the purpose of allowing movement of the arm 160 upon the lowering ofthe slide 154. By .the above means the detachable `accounting devices are latched within the machine. At the proper time the cam 167 causes the arm 160 to be rocked away from the shoulder 158, permitting the slide 154 toV rise under the action of its spring 186 thereby permitting the detachable accounting device to be ejected from the machine by the arm 155 under the action of the spring 157, the latch 150 being rocked out of engagement with the shoulder 151 of the detachable device when a. shoulder 168 ot' the latch engages a' shoulderlf) of a spring pressed pawl 170. This pawl is permitted to rock upon its pivot against the action of its spring upon the inward movement of the latch 150 but is prevented from rocking when engaged by the shoulder 168, by a lug 171 on an arm which is fixed against movement upon a pin 173. j

lf it is desired to reset the amount slides of the detachable accounting devices at the time the totals of the same are printed, it is merely necessary to depress a key 174 which is carried by a slide 175 and is retained in its pressed position by a pin 176 which is carried by the slide and may be pushed into a hole 177 in the shank of the key. The depression of the key 174 causes its yshank to enter a. slot 178 in a plunger 179 between an end 180 of the slot and an arm 181 which projects into this slot. The arm 181 is carried by a shaft 182 and is oscillated upon each operation of the machine by a pitman 183 which connects an arm 184 on the shaft with a cam 185 on the drive shaft 42. If the key. 17% is not depressed the arm 181 will idly slide in the slot 178 of the plunger but when the key is depressed the plunger will be projected forwardly into the opening 7 of the detachable accounting device causing its ianged plate 3 to be rocked out of locking engagement with the denominational slides 2. This occurs after the printing operation, but before the unlatching of the detachable accounting device. The springs 12 forcethe slides 33 to thei` upper or zero positions thereby causing the denominational slidesof the detachable accounting device to be pushedto their zero positions against the action of their springs. ll'hen the detachable device is reset it is retained in the machine slightly longer than usual in order not to rely Wholly on springs 12 to do the work of resetting but to permit restoring cam 94 (Fig. 5) to do the work if necessary. To provide for releasing the detachable device at the time required when it is reset, releasing cam 167 (Fig. 9) is constructed to operate pitman 164. a second time when the drive shaft has rotated about 225 degrees. On such resetting operation the first releasing operation of the cam is ineffective by virtue of the engagement of plunger 179 with the retaining device. Before the unlocking of the denominational slides of the detachable device the notches 10 in the identifying blades 8 must be brought to coaeting relation with the flange 9 of the locking plate 3. Thisv is accomplished' by alining the type carriers which are under the control of the identifying blades i. The alining ot' the type car- 'riers is accomplished by pawls 186 (Fig. 2)

which coact with almmg segments 187 which are fixed to these type carriers. The pawls 186 are carried by shaft 82 the means for oscillating which was previously described.
